Wet oxidation via two-phase flow reactors and high mass-transfer regimes

Abstract

This paper describes an approach based in the creation of a high interfacial area flow regime via a jet mixer. The latter is a device that permits the dispersion of the liquid phase into fine droplets. The establishment of a mist-type two-phase flow leads, in a few minutes, to rapid oxidation of the organic compounds in a kinetically controlled regime. A compact oxidation technology based on jet mixers and tubular reactors is thus achieved. The results obtained with prototype phenolic and glycol solutions and, also, with industrial wastewaters are discussed.
